Is condition is necessary before releasing instance

Anonymous User 1333 03-Nov-2015

Whenever I release any instance that could exists or not, I am using this code:

if(myObject!=nil)
{
   [myObject release];
}

but I have a confusion, sending a message to nil is not a problem;
I want to know, is that condition necessary?

There is no need to check nil, because by default Objective C checks for nil,
So there is no need to check it twice.

[myObject release];
 myObject = nil;

but, you can do some extra code with that object here, before releasing the object.
